There are far too many characters in the Marvel Universe to come to a conclusive answer for this question, especially being asked to choose the "second" most powerful hero, lol.
The second most powerful *character* would have to the Living Tribunal, who is subordinate only to the One Above All(and both of whom may-or-may-not be Celestials in other forms: the One Above All shares the same name as the Celestial leader, and the Living Tribunal would be Arishem the Judge, etc).
But as for *heroes*, the scale goes all the way down the line from there, lol...complicated again by having to choose the *second* most powerful hero, then deciding who to consider as "heroes", etc.
******
the most powerful characters are all from marvel, and they are...
1.beyonder
2.sentry
3.red hulk
4.devil hulk
5.mephisto
so i guess the second most powerful charector is sentry.
