Depends at how much you want to improve and what your schedule looks like because chill comes before chess. That being said maybe do 15 mins of puzzles a game or 2 (15|10) then study for 15-30 mins for now. What I do is somedays ill do puzzles some days ill do end games somedays ill watch videos so I don’t have a set schedule.
How much time to devote to studying each part of chess at 1600?

you play on chess.com two hours daily
I already play for more than 2 hours
Akshath118 - If I'm online, you can challenge me and I'll probably accept unless I'm busy. I don't mind coaching you for free.
I would recommend having a payed account (I have gold), so that you can analyze and study opening explorer.
You are 1400-1600 +, so I would recommend that you make sure you have a strong grasp of your openings. Also, I would say that just solve as many puzzles as the chess.com will allow you to solve per day and play games and analyze the rest of the time.
I think ChesswithNickolay makes a good point. For 1600, you guys are far more likely to blunder or lose in the middle game than the endgame. Once you are able to play so well in the middle game, your rating will go up. At my level (2300), we can play consistently with >90% accuracy, so that allows us to reach more endgames than 1600s would usually reach.
SECOND: @ChesswithNickolay: 80% + 40% + 20% + 10% + 10% + 20% = 180%. That's not possible.

I don't know how much time you have, but do 2h tactics 1h openings 1h/2h playing and the rest (as much as possible, preferably 5+ hours) with books and a chessboard.

But realistically you won't have that much time, so just focus on tactics and books as much as you can

Hi, I'm a 13 year old chess player who is currently 1600 in rapid and 1400 in blitz. How much time should I spend approximately on solving puzzles, studying openings and endgames, and playing actual games?
Depends...
Depends on what your goals are.
Depends on what you mean by "improve"
If your goal is to get better at online speed chess, then just hit tactics, and nutty openings hard.
If your goal is to improve in OTB tournament play? Youre going about improving wrong.
I am 1600 rapid and we still leave our Queens en prise I think 1600 are just beginners who have started to grasp the tips given to 800's.

At 1500, I spend my time trying out different openings so I can see first hand what the strengths/weaknesses are with each of them first hand. Reading about them doesn't sink in. It's cost me ratings but helped me determine which openings work best for me. To do this, I read and watch opening videos to see different tactics with the opening. Middlegame improves by doing puzzles and playing games. I try to play at least 5 games/day (15/10 or 10/0). Most games end long before the time expires. I find it important to keep it up daily though. If you stop then the knowledge is lost. And I agree with an earlier comment, if your rating is still improving then don't change a thing and continue with what you're doing.
