Hi, I have made the data with this command:

featureCounts -T 64 -p -t exon -g gene_name -a ~/data/human_genome_rf/Homo_sapiens.GRCh38.102.gtf -s 0 -o featureCounts_S_2.txt .bam .bam 

I have .txt output, (not really readbly to paste in here) which I could read in R by DGEList() command. I would like to perform DE analysis and then make some plots and compairing. Coud anyone give me some advice how to parse that data? I d not know really what to do next to do it good.

Please help.

Did you read the manual?
https://www.bioconductor.org/packages/release/bioc/vignettes/edgeR/inst/doc/edgeRUsersGuide.pdf

It is outstandingly comprehensive. Please try that first and then ask a more specific question.

If I want to perform DE analysis with edgeR, what kind of table (data) I have to had? I mean structure of data? Could you help? And if I have more than once sample (table with DE) how to compare it? Is that question is clear?

I am not going to spoonfeed you. Read the linked thread and the edgeR manual. Really, it is all in there.
