● "\My German Shepherds dont like people, why?"
Your very next sentence explains WHY.
● "When I first got them they were very timid puppies, and would hide from everything and everyone."
That indicates that:
#1: They had genetically inadequate natures and
#2: had been VERY poorly reared, almost certainly with punishment used OFTEN and praise & reward almost never.
And so sensible people declined to buy them, so the pups never got anything GOOD in their life until they reached the rescue group.
To make it worse, YOU accepted at least 2 of them at the SAME TIME!
The "rule" for sensible people is
"Do NOT look for a second pup until the first one is confident, well trained, neutered and healed. And you then look for a pup of the opposite sex".
● "I've had them from nearly a year, and they will be a year old this coming Monday. They love me, my mom, and other females they knows... "
Because they have learned during those 10(?) months that you feed them and make a fuss of them - quite possibly the visiting girls/woman do the same.
● "but they start growling at men and women whom they dont know."
Naturally - their inborn instinct is to fear everything they don't know, so they snarl in hopes it will scare the possibly-dangerous stranger away.
However, the BIG danger is that when a fearful pooch cannot escape (such as trapped in a corner) as in these cases:

and

- the FIGHT part of "Fight or flight response" takes place until the fearful pooch thinks its can escape. You having TWO pooches like that, you are extra dangerous, as they will react to each other's fear.
● "They know my brother, but they still dont like him."
Don't ask US to work out why - but I'll bet that YOU have a pretty good idea. It is even likely that YOU don't like your brother! (Quite probably the other animals on your property don't like him, either.)
● "Why are they like this? They are very well behaved and trained,
Oh really? So you've been getting coached in a weekly training class for the last 9 months, have you?
Are YOUR dogs as well-controlled and patient as these?

● "But I'm unsure how I'm suppose to get them use to people without showing aggression."
You can't - not until they TRUST you fully, and you have secure control using your voice commands and your hand.body-signals. And the BEST place to achieve that is in a training group with an experienced coach. But you will need to first meet that coach privately, so that he/she can assess each of your dogs (while the other is securely in your vehicle), sees how each of them is around his/her best-trained dogs, and decides which is best for you to leave home until you have the other under proper control and the other dogs & people in the class are safe from being attacked by your fearful pooch. Until you HAVE that control, you dare not let them off-lead near other people or dogs. And you won't be strong enough to control TWO adult GSDs, so you can't afford to walk them at the same time. Tough on you, but you made the decision to get a fearful pair. It saved their lives - but is the result worth the drawbacks and risks?
I consider that the only dogs worth having are bold, calm, curious, and fearless.

The people in them KNOW about GSDs. Plus you can include several actual photos in your posts.
