A few hand (.25/.50)

These are from a homegame so no real hh , i remember the board/estimated stack sizes though. Just the hands that are left on my head and wondering if i played them ok. I exclusivly play sng's online but do play a lot of cash homegames/some casino $100 max (50bb deep)

Hand 1:
SB($15)
BB($20)
UTG($35)
MP($25)
CO/HERO ($25)
BU($35)

Hero is in CO with (AKo)
Sb/BB posts , UTG Straddles $1 , MP folds , Hero raises $1.50 ($2.50 including straddle) , Bu folds , sb folds , bb folds UTG calls $1.50

FLOP 3 , 4 5 , (rainbow) (Pot $5.75)
UTG checks , Hero bets $3.50 , UTG calls $3.50
Turn 7
UTG Checks Hero Checks
River Q
UTG Checks , Hero????

Do i fire a 2nd barrell on turn , or take the free card and hope to hit a 2/A/K assuming these are all good cards.
River ? Do i bet if i think i can get him off something like middle pair or check since i have some showdown value if he also called flop bet with just a bare ace?

Hand 2:
UTG/CO ($20)
BU/HERO ($20)
SB
BB ($10)

Hero is on the BU with 10 , 10
UTG calls .5 , Hero raises $2.50 SB folds , BB raises to $10 and is all in , UTG calls $9.75 , Hero shoves the rest in?
Ok to reshove here? UTG/Co is loose donk who would call that $10 with just about any high card so and will definitly call my $11 more or whatever it is , so even if im dominated by BB (who is also loose) i will be able to break even vs Co (if i lose main pot but win sidepot) which was my thinking process.

Hand 3:
BB ($15)
SB/Hero ($40)
UTG ($11)
CO ( $35)
BU ($20)

Hero is in the Sb with ( 9 , 9)
UTG raises to $1.25 , Co calls $1.25 , BU calls $1.25 , Sb (HERO) calls $1.00 , BB calls $.75?
Calling ok? Or reraise?
Flop , 2 5 , 7 (rainbow)
UTG bets $1 , CO folds , Bu folds , Sb / Hero calls $1 , BB folds.
Turn 9
Hero checks , UTG checks
River J
Hero bets $3.50 , UTG folds.

Should i have reraised flop? This is the first hand UTG raised (weak .75 raise btw) so on the flop i either figured he missed or had a overpair too which probally beat mine so i figured if i was either pretty far ahead and a raise would knock him out or i was behind. Turn i checked hoping he would bet again since he is a fairly agressive player , ok?
River v-bet ok?
