As many as God Created

1,000,000,000 stars per galaxy. we've seen probably about 50 billion galaxies
so we've got
50000000000000000000 stars lets say

guessing there is a 0.0000001% chance of life compared to the stars we have then we've got
5,000,000,000,000 (5 trillion)(stars) that might have a planet that could be able to support life

lets do another 0.0000001% on the result of the 5 trillion possbile stars
that still leaves us with 500,000

I'm still using very very very small chances but have come to a pretty high number.

sounds pretty likely to me that there could be 10x more than what I guess.

most of my starting numbers are guesses, but I think I was reasonable in my guesses...... still,
The odds are "astronomical" that there is life out there some where

if there are

At least 3,259, probably more.

Given that there are more than 200 Billion Stars in our Galaxy which can have from 0 to 10 planets with their assiciated moons orbiting around them, and thousands and thousands of other galaxies out there beyond our Galaxy, each of which might contain billions of stars with each one having the capacity to have from 0 to 10 (or more) planets (with their associated moons) orbiting around them...3,259 is a relatively small number to suggest...probably a bit on the low side.

I have of course excluded all of the planets within our Solar System because it is fairly certain that none but Earth have the necessary qualities to sustain life as we know it.

in our solar system there is one PLANET that has life, theres pretty much no chance with mars. but saturns moon titan and jupiters moon europa are both thought to have some microbial life below the surface.

but outside our universe there is most definately billions. there are billions of galaxies, each with billions of stars. thats over 1,000,000,000,000,000,000 stars. if we assume each has 9 planets (thats wrong some have more some have less some have none) then we can assume there are 9,000,000,000,000,000,000 (or 9 quintillion) planets. and trillions more moons and many many many more comets and asteriods. the possibilities are so vast, its selfish to think that 1 in 9 quintillion planets sustain life, thats a midevil type belief, like the earth being at the center of the solar system, its self centered.

What sort of life, and with what technology to make it habitable?
I don't doubt that one day we'll be capable of making other planets livable, and there are countless billions out there.
Also, perhaps life can be made of a number of chemicals other than what makes life on earth. We have no way to know, so we should keep an open mind.

In our solar system? Possibly 2 or 3 (Earth, maybe Mars, maybe Europa though that's actually a moon).

In our galaxy? Probably hundreds of thousands or even millions.

In the universe? Billions.

I don't know how many but I'd say it's one planet for a solar system like here.

Thousands. Maybe millions.

Billions, but God had nothing to do it.
