  1. the text (box label) is to be made bold,
  2. the box scales for the 3d plot is also to be made more bold

Kindly suggest me the syntax.

Hi Rahul,

Using Epilog for the axis labels is not a good idea. The labels do not follow the axes as the plot is rotated. Use AxesLabel instead.

AxesLabel -> (Style[#, 14, Black, Bold] & /@ {"\[Xi]", "K", "\!\(\*SubscriptBox[\(\[CapitalOmega]\), \(r\)]\)"})

To make the plot legend bold

PlotLegends -> {Style["Real frequency", Bold]}

To change the tick style

TicksStyle -> Directive[Bold, Black]

Result

Plot3D[Re[x], {xi, 0.1, 1}, {k, 0.1, 1}, 
 BoundaryStyle -> Directive[Blue, Thickness[0.007]],
 PlotLegends -> {Style["Real frequency", Bold]},
 AxesLabel -> (Style[#, Black, 14, Bold] & /@ {"\[Xi]", "K", 
     "\!\(\*SubscriptBox[\(\[CapitalOmega]\), \(r\)]\)"}),
 Mesh -> {{0}},
 BoxRatios -> {1, 1, 0.4},
 BoxStyle -> Directive[Black, Thickness@0.006],
 TicksStyle -> Directive[Bold, Black]]
