I got curious and visited the journal website (JIBS) you linked in a comment. I won't comment on the reputability of the journal in question, but two things stand out
The publication process seems rather outdated, and
The journal appears to be a small operation, possibly run as a passion project. (Note that individual issues are sold for a reasonable £10, and that the website doesn't appear to be up to date.)
To me this raises the question of whether the journal has sufficient readership to provide visibility for your work. If it doesn't do that, why go through with the arcane submission requirements? This is something you might want to discuss with others in the field, which also helps gauge the journal's reputation.
If you want to go through with publishing in the journal, then you likely will have to work on their terms. The submission guidelines seem clear on how they want things (not) formatted:
d. JBIS requires papers to be submitted in an electronic form compatible with PC formats. We can handle Microsoft Word for Windows up to version Word 2010. A PDF version of the paper would also be helpful to aid formatting. Authors are asked not to use auto-formatting, footnotes, headers, footers and other advanced features and keep the manuscript as close to a pure text file as possible. The exception to this is that it is helpful if mathematical equations are formatted in an equation editor. Please note that any formatting you introduce will have to be removed by the Editorial team for our own formatting process, so using your own formatting does not assist the process.
Suffice to say, the highlighted parts are not the hallmarks of a modern, somewhat automated publication process. Then again, if it is a small operation it's hard to judge them for not spending frivolously on software licenses and updating their processes.
As for suggesting referees, this is common in some fields, uncommon in others. Generally they shouldn't be from the same organization, or a direct collaborator. Avoid suggesting referees that, if acting ethically, might have to disclose a conflict of interest. Again, there is some discussion of this in the journal's submission guidelines. There is no guarantee that the editor will use either/both of the suggested referees.
