Sicilian Defense is NOT what I would call a beginner opening. It contains a LOT of theory. Beyond that, I can't help you much since I'm bad with openings, but Queen's Gambit is a good one to know as white (and the responses by black)
Beginner Chess Openings?

More or less. But it's so common, it's a need-to-know IMO. I wish I had known it earlier, at least. The Sicilian took me a lot longer to learn, though.

Ruby Lopez sounds like a latino hooker.
Both the KG & Ruy Lopez are rock solid but like any ancient opening have masses of theory.

King's gambit isn't what I would call rock solid, but it is very playable and if you are a good attacker than go for it.
Good beginner openings are stuff like the italian game, the two knights defense, queens gambit declined maybe... It is best when starting out to play 1.e4 as white, and answer 1.e4 with e5 and 1.d4 with d5 in my opinion. You can learn alot about chess from these classical positions, and the moves are usually fairly logical aswell.
So I normally do
White: Evan's Gambit, Italian Game.
Black: Two Knights Defense, Silician Defense.
Does anyone know any other openings that would be good for a beginner?

I have to agree, your choice of openings are *not* what I would recommend for a beginner. WAY too much theory and too many different lines available. e4 e6 (the French, as one member recommended) is good, e4 e5, d4 d5... etc.
I recommend simply getting a pawn (or two) into the center and making solid, common-sense moves until the general idea of square control and tactics are clearer.
Besides, the Grandmasters STILL play these openings, so they are 100% sound and your winning chances are good.

Here's what I would recommend for a beginer.
As white 1.e4
1...e5 2.Nf3 Nc6 3. Bc4,Nc3,d4 are all fine. The only openings I would avoid are the ruy lopez and the kings gambit. The ruy is a deep opening it's easier to understand after playing lots of Italian type games. As a beginer you just want to make to the middle game and have a playable position, to do this you will need to castle early. The Kings Gambit weakness you kings position, although it leads to many interesting positions, there is no need for a beginer to seek such complex play on the second move.
1...c5
I would play either the morra-smith gambit, 2.d4 cxd4 3.c3 or the 3.Bb5 sicilians.
1...e6
the exchange varation will do just fine 2.d4 d4 3.exd5 exd5
1...c6 again the exchange varation will be fine.
against any hypermodern opening just develope naturually and try to control the center.
as black:
After 1.e4
1...e5
2.f4 d5 3.exd5 exf4
2.Nf3 Nc6 3.Bb5 Nge7
2.Nf3 Nc6 3.Bc4 Nf6, or Bc5 are both fine
After
1.d4 d5 2.c4 e6 play something like the semi-tarrasch defense

So as of now, my current openings are:
White: Scotch Game, Evans Gambit
Black: French, Petrov Defense
Anyone wanna add or subtract?

for a super beginner, i'd learn the ruy lopez for white (if it sounds like a mexican hooker, you can also call it the Spanish game) or maybe the english opening if youre feeling frisky.
for black, Caro-Kahn is pretty good, i like the french
As a beginner, start with 1-move openings and play the rest by logic.
Then, move on to 2-move openings.
After that, learn 1 more 1 move opening.
For defenses, try to do a similar process.
The Petrov Defense is the most solid defensive response to 1. e4 e5 2.Nf3. However, if you are still developing your feel for tactics, you can fall into a few "traps" that can be damning.

Your openings are fine. As a beginner, you want something that's active and open, and the ones you play serve that purpose perfectly well. (Much better than the French defense, for instance. ) Don't worry about switching to something else; your study time is better spent elsewhere.

As for the comment about the traps about the Petrov, I know all about them and have actually pulled them on quite a few people, as both black and white, so I'm good in that area.
Really? Most beginners wouldn't know the Kholmov Gambit.
What do you mean when you call yourself a "beginner"?
Either way, if you know the "traps" well enough to exploit them as Black, then marveliosity was wrong to tell you not to play it. It's solid and played at the very highest level of competition, yet it is very simple.
Did you look at the variations? Including the different moves after 5.d4? I think choosing one of those would be a nice starting point for adding the defense to your repetoire.
So I normally do
White: Evan's Gambit, Italian Game.
Black: Two Knights Defense, Silician Defense.
