Two hands where I ended up all in

Hi this is my first post here, so sorry if anything is wrong!!

These two hands I ended up all in with. I am not sure if they were played correctly or not. I am looking for advice on how more experienced players would play these hands. Thanks!

This is $2/4 NL and everyone has round about $400 stack. Both hands are against unknowns.

Hand 1:
Two limpers and I call in MP with 8s9s
Three more people including the blinds call, so 7 see the flop.
Flop is TsJsKs (Pot $28)
Checked to me and I bet $25, just the person on the button calls.
Turn Ac (Pot $78)
I bet $67, button calls.
River 8h (Pot $214)
I bet $120, button moves all in for about $200 more, I call.

I wanted to fire a value bet on the river because I figured the most likely holding is a Q. I was unsure what to do when I was raised all in here.



Hand 2:
Three limpers, I call in CO with 4h5h.
Button raises to $20, two limpers call, and i call. Four see the flop.
Flop is Js4s5c (Pot $84)
Checked to me, i check, button bets $70. All fold to me and I call.
Turn 9h (Pot $224)
I check, Button bets $200, I move all in for about $100 more, he calls.
