Can you be saved in this life?
If you correctly believe you must endure to the end (keep salvific faith till death) then logically, you cannot be saved till you die; thus, you cannot be saved in this life time. This doctrine is debated.
Aside: I've wondered what happens to a person with Alzheimers who forgets his faith.
Sucks to be him I suppose.
Aside: I've wondered what happens to a person who has faith and loses it in a continuous cycle. Then salvation becomes the luck of the draw ... did the person die during a period of faith on disbelief? In a perverse sense, it would be beneficial for a person to commit suicide while a believer to ensure a heavenly destiny. This eliminates the possibility of dying later while an unbeliever and its eternal devastating consequences.
If you correctly believe God chose you and is the cause of your salvation AND you believe in the eternal security of God's chosen then, in a sense you were saved before the foundation of the earth. The actual physical consummation of salvation being the point at which the Spirit regenerated you. There is NO chance you will be lost. You were therefore saved during this life in the sense it was consummated while you were alive.
also can you be saved without a priest?
Yes, at least in the sense I think you mean it. (thinking Roman Catholic theology)
This is not to say a priest/pastor/father/friend may not be God's instrument whereby one hears the gospel which is a prerequisite to salvation. (salvific faith cometh by hearing)
One CANNOT be saved without knowing the gospel of salvation which includes knowledge of Christ, so in a sense, since God uses men to spread the gospel, men are needed by your salvation as a secondary cause.
Aside: There are some on this site who do not believe you need to hear the gospel (need to know of Christ) to be saved. If that is true, then no person in any respect is needed for one to be saved.
