Looks Like you have a VM with two snapshots, identified by the 0001 and 0002, the first snapshot is approx 35GB, and the second snapshot is very small.

If you want to revert to the initial state of the VM, select Go To and select the Snapshot you want to Go To.

and the delete the remainder.

If you want you can read my EE Article

If I see many snapshots in the snapshot manager, for instance 5 snapshots, and I want to revert to the one in the middle and delete last 2 ones and first 2 ones?

I will use : select the one in the middle and click on GoTO.

at this point the only one will merge with base image is the one I selected for GoTO
after then If I delete other ones would they merge or get deleted?

Also
if I see in the Snapshot Manager:

Vmname.domainname.
 *Snapshot1
   * You are Here.

in this case if I select Snapshot1 the click on GoTo, or If I delete the snapshot, then in both cases it will merge the snapshot to the base image?

if you select Go To the 3 Snapshot, you would delete the two after, there is no need to delete the first two, you would Delete All, which would merge the Third snapshot with the first two, and all snapshots would disappear.

snapshots are linked

Parent - Snap1 - Snap2 - Snap3 - Snap 4 - Snap5

you cannot delete Snap1 and Snap2, without it deleting Snap3.

think of it as links in a chain. All the links must exist, otherwise the chain breaks.

you can discard snap 4 and snap 5 because they are after snap 3.

if you Goto Snap 3, delete snap 4 and snap 4, and then delete ALL, merges Snap 3 into Snap 2 into Snap 1 into Parent.

in your last post, you are correct. It's really called a Snapshot Chain.
