Closing the betting round

This is an important concept that a lot of times begginer players do not consider. When you are calling a raise, are you closing the betting round? That means, can somebody raise your call in the same betting round? If not, that call does not guarantee you to see the next round for the ammount of the call, you risk to have to put more money or fold on this same betting round.
Another point, how likely is that someone raise my call?
I will try to explain this with a hand.

CO ($5.92)
Hero ($1.41)
SB ($2.60)
BB ($2.34)
UTG ($1.33)
UTG+1 ($14.80)
MP1 ($11.24)
MP2 ($4.64)
MP3 ($5.50)

Preflop: Hero is Button with 8s, 8h.
UTG calls $0.02, UTG+1 raises to $0.1, MP1 calls $0.10, MP2 calls $0.10, 1 fold, CO raises to $0.18,

This is the point I'm talking about. So, I'll go again thru the hand to analyze it. UTG flat calls, UTG+1 raises to 5BBs, MP1 flat calls, MP2 flat calls, 1 fold, CO re-raises to 9BBs.

Now I have 88, and have to decide what to do.
Can I flat call? First of all, I will not be playing deep (my stacks is not even a normal full buy in of 100BBs). Second, we have to analyze how likely is that this 9BBs call can take us to see a flop. I'll have two players behind, SB and BB still to act that still didn't showed anything about their hand strength. They are not a high risk. UTG has limped, so altough he might had limped with a monster pair, is not likely, because two other players have showed a lot of strength so they probably are holding big cards and so reducing the odds for UTG to have a monster pair. Now we go to UTG. He is playing for a full stack, and with a limper in front he has decided to open for 5BBs in second position, with 7 players still to act. So, most probable he either has a very strong Ace or a big pair. So, can he re-raise here? Yes, it's a very possible situation. I don't see MP1 and MP2 as a threat, as they flat called the opener, they are probably saying that they want to see a flop but they fear the opener is ahead now.
So, the main risk here is the opener (UTG+1), and he is a real risk so I decide to fold.

3 folds, UTG folds, UTG+1 raises to $0.66,

The risk has materialized. Now if I had called, the 9BBs can not get me to see a flop, it will either be 33BBs at least, a fold or a push. And here pushing or calling 33BBs does not make sense, so I'll had to fold, and lose the 9BBs investment without seeing any card.

MP1 folds, MP2 folds, CO calls $0.48.

Two players see the flop for 33BBs.

Flop: ($1.57) 2h, 2s, 7s (2 players)
UTG+1 bets $1.6, CO raises to $5.26, UTG+1 calls $3.66.

Turn: ($12.09) 4d (2 players)

River: ($12.09) 3s (2 players)

Final Pot: $12.09

Results:
UTG+1 has Ad As (two pair, aces and twos).
CO has Tc Ts (two pair, tens and twos).
Outcome: UTG+1 wins $12.09.
