Default Chip-seq data questions

I need work with Chip-seq of 3 conditions (WT, C and V). It’s single-end.
When I saw the data, questions born:

1. Each sample has duplicate, but each duplicate has 4 fastq files corresponding to “lanes” of the sequencing. That’s mean that the 4 files correspond to one sample? If so... Would I join the 4 fastq files for work with them as one sample?

2. Other sequencing data are present, with names WTIN, CIN and VIN (each one with 4 fastq files). The text file that I received says: “Each experiment was performed in duplicate, the sequencing was through NextSeq with a 76ntSR reading format, single entry income for each sample marked as WTIN, CIN and VIN.” Someone known whats that mean?

Thanks to everyone!

1- Libraries has been sequenced on a NextSeq flow cell that has 4 lanes so the data from lanes for each library needs to be merged into one file for each sample replicates for analysis.

2- You need to clarify this with data supplier. The terms "WTIN, CIN and VIN" simply could refer to your sample names for WT, C and V, respectively. I would normally name them as WTIN_1, WTIN_2 ... to identify each replicate.
