Hey there sweetie,
HUGS HUGS HUGS.
Look I am not really a good person to help here because with my DS I continued to feed overnight when he woke until he was 12 months old. He had reflux and I believe most of the time it was more about comfort than true hunger, but it did mean I didn't have to have my brain plugged in at the middle of the night. I also APOP my little man because I knew that most of the time he was in pain, so I just cuddled him.
I think in your case sweetie I would have a good think about how you want to approach these night wakings and have a clear plan about how you are going to deal with them (so you don't have to think too much in the middle of the night LOL)...
...if she is 95th percentile it is highly likely that sometimes she is hungry and the fact that she is waking at different times is actually a good thing because it means her wakings aren't habitual.
- At this time our little man started teething and he did not teeth well, the screaming that you are describing sounds pretty familiar to me....have you checked her mouth, does she usually have issues with teething. If yes then do try giving some paracetamol before bed time or some gel on her gums when she wakes to see if it helps.
- If you think she has high sleep needs on those days that she doesn't get as much I would definately APOP and take her for a pram walk or a car ride to "top her up"....OT babies sleep so SO badly.
- I'm not an expert on dream feeds, but I'm pretty sure she shouldn't be needing this one now sweetie...if she is hungry at this stage I would be surprised (esp considering she is eating her solids well)...perhaps this habitual wake is mucking up her sleep cycles??? I would probably try doing some PU/PD here if you decide to drop this, but perhaps get some advice from other mums who have done dream feeds

Sweetie you should NEVER feel guilty if you get your LO back to sleep then they wake hungry, there is nothing wrong with doing this...she will let you know when she is hungry and she will never starve, so stop feeling bad!! You are doing your best in a very tricky stage, so many developmental, physical and mental developments going on...you are always one step behind, you are not alone in that one!!!

When she wakes I would look at the time, if it's before say 2am I would probably try and get her down without feeding, but if she is obviously looking for the boob then feed

I would try and do PU/PD for these wakes as long as you are sure that she isn't waking from pain (look at her body language and listen to that cry, she may be getting windy from the solids or teething)...if you think it's pain just cuddle her sweetie and calm her down, take a bit of a soft approach for a few days and see if it helps.
Sorry I can't be more helpful and I'm sure there are heaps of things I haven't addressed, my main point is to have a little mental check list so you don't feel like you are struggling so much and have a clear idea of how you will respond to what behaviours....
good luck
hugs
