“最早周五给你”英语怎么说

I will give you Friday as quickly as I can.

It'll be ready on Friday at most

I'll not give you until Friday at the earliest.

I'll not give you until Friday at the earliest

The earliest I can give you (this) is Friday.

OR

I can't deliver it till after Friday.

you'll get it on friday at least（the earliest）
首先，句子的主语不能用I，这是个非指定的主语，而英语如果把动词放在前面就变成祈使句了，所以，这个句子you来做主语。
I'll not give you until Friday at the earliest---这个句子意思可以，但是口气太生硬
